Specification of Letters Patent.

Application led July 12, 1913.

Patented Feb. 10, 1914.

serial No. 778,788.

To ZU ywhom [t may concern Be it known that I, ANTHONY J. BAULIG,

a citizen of the United States, residing at Home, county of Oneida, State of New York, have invented certain new and useful Improvements in Butiing-Machines, the following being a full, clear, and exactdisclosure of thc one form of my invention which I at present deem preferable.

For a detailed description of the present form of my invention, reference may be had to the following specification and to the ac'- companying drawings, which illustrate my invention, wherein- Figure 1 is a side view of my machine and Fig. 2 a vertical section thereof.

My invention relates to a machine for producing on brass bedsteads what is known as a velvet finish which has heretofore been produced only by hand. In that finish there is on the surface of the brass a slight trace of lines'running circumferentially around the tube and while it can be produced on a straight length of tube by putting the tube in a lathe and applying lan abrading such as emery cloth to it as it rotates, yet in brass bedsteads the tube must be bent, previously to its being polished or finished, into the .volte form required for-the end frame of the bedstead, and after being so bent or shaped it can not be swung in a lathe, hence this particular nish has always been produced by hand.

My invention resides in a rotating ring rcarrying within it a tubular bufting device and rotated by an external belt. Thus as the ring and batting device rotate, the tube to be finished can be introduced axially into the butiing tube and, without being itself rotated, can be passed slowly through the said tube which produces on its surface the velvet finish above described. Moreover, the emery cloth within the buiiing tube isso mounted on a yielding support or backing of felt that the bent or elbow portion of the tube can also pass through it, even if the bend includes a curve of 90 degrees, and the bent or curved part will receive the same finish as the straight portion'.

Referring to the drawing, A is a ring or annulus having a reduced portion A1 on each side thereof forming a hollow or open jourual mounted to rotate in bearings B, B.y The. outer periphery of ring A is slightly v gether.

crowned to give it a pulley surface for a b elt F by which it is rotated. lVithin the ring A is mounted a two-part holder C, C1, each part being provided with ears c, c by which the two halves may be screwed to- The holder is removable sidewise from the ring A which has a horizontal groove a on each side into which the ears c c of the holder may pass. Screws D, D]L pass radially through the ring A into the holder to center it in the ring while allowing it some play.

G is a layer of thick felt cloth within the holder and H is a layer of emery cloth or other abrader wit-hin the felt. By removing the holder and separating its two halves C,

C1 the felt and emery cloth may be bent into tubular form and laid betweenl C and C1 which will then be screwed together and thereby have an adequate hold on the felt and emery cloth. The holder will then be inserted in ring A and secured therein by the screws D, D1 so that. as the ring is rotated by belt F it will carry with it the holder C, C1 together with the tubular felt and emery cloth secured in the holder. Then as the brass tube E is inserted axially into the ring it will enter the butting tube and the emery cloth will bear thereon and by virtue of its lrotation will produce on the surface of the tube the desired finish. When the bend or elbow of the tube is reached the felt will yield sufficiently to allow it to pass through and be acted on by ,the emery cloth in the same way as the straight portion.

lVhat I claim as new and desire to secure by Letters Patent is:

l. A buiiing machine comprising a ring or annulus open at both ends, journal bearings therefor outside of the axial opening therethrough, and means for securing buit'- ing material on the inside of the ring.

2. A butiing machine comprising a rotating ring or annulus open at both sides, journal bearings therefor outside of the axial opening therethrough, and a bufling tube therein provided with a yielding backing.

3. A butting machine comprising a rotating ring provided with an axially open journal and bearings therefor and an internal holder removable vlaterally through the open journal.

4. A butiing machine comprising a rotating ring provided with an axially open journal and bearings therefor and an internal two-part holder removable laterally through the open journal. l

5. A buing machine comprising a rotating ringprovlded with a hollow journal and bearings therefor of a holder within the ring, an abrader carried by the holder and a yielding support for said abrader.

6. A buliing machine comprising a rotating ring provided with a hollow journal and bearings therefor of a removable holder within the ring, means for securing it centrally therein, and a tubular abrader carried by said holder.

7. A buthng machine comprising a ring provided with a hollowjournal and bearings therefor of an operating device applied to the outside of the ring and aremovable and yielding tubular buffer vin the ring in line with the hollow journal.

k8. A buiiing machine comprising a rotating ring havin a hollow journal and bearings therefor o a removable two-part holder within the ring, means for securing said holder in said ring and a tubular abrader having a yielding backing mounted between the two parts of said holder.

In witness whereof I have hereunto set my hand, before two subscribing witnesses, this 30th day of June, 1913.

ANTHONY J. BAULIG.
